函数说明：
nodeName： 流程上一个节点
示例：
实现getUserFromFlowNode(nodeName)函数的应用
function getUserFromFlowNode(nodeName) {
        var userProcess = getUserProcess();
        var userList = createObject("java.util.ArrayList");
        var doc = getCurrentDocument();
        var domainid = getDomainid();
        var sql = "select max(id),auditor as item_auditor,'" + domainid + "' as domainid from t_relationhis where docid='" + doc.getId() + "' and startnodename='" + nodeName + "' group by auditor";
        var datas = queryBySQL(sql);
        for (var it = datas.iterator(); it.hasNext();) {
                var data = it.next();
                var userid = data.getItemValueAsString("auditor");
                var user = userProcess.doView(userid);
                userList.add(user);
        }
        return userList;
}
